A mounting bolt for use in mounting toilet stools has upper and lower ends with an elongated threaded shank therebetween. An elongated planar head is on the lower end of the bolt and has a width similar to the diameter of the shank, and a longitudinal length larger than the diameter of the shank. The head has a center axis extending along its length. An indicia mark is on the upper end of the bolt visually indicating the position of the center axis to assist the placement and tightening of a threaded nut on the upper end when the position of the head is concealed when the nut is being threadably mounted on the upper end of the bolt. The method comprises aligning the indicia mark in a direction transverse of the narrow portion of an elongated slot in a floor ring so as to enable the installer to simultaneously position the long dimension of the planar head in a transverse direction with respect to the narrow portion of the slot to permit the head from pulling through the slot when a tightening bolt on the upper end of the bolt is used to tighten the base of the toilet stool to the floor ring.
